My (business) notebook has two graphics cards, one builtin identifying as Intel Iris Xe and an additional one, a Nvidia MX550. I start X11 (xwin) with defaults (-listen tcp is the only extra option). Using nvidia-smi and the Nvidia activity dialog i see that the Nvidia graphics card is not used. Using glxinfo i see that the builtin Intel Iris Xe is used instead. I already prefer Nvidia over Intel via the Nvidia control panel. How do i make X11 and OpenGL use the Nvidia graphics card instead of the Intel one?
